Bunch of stuff learned today.
Load with zinc pop can size round ball for 100 yards was 250 grains of Cannon grade. 250 grains of Fg sends the ball in excess of 200 yard...I say in excess, because the cut grass went 200 yard and it was tall grass beyond that, and that's where I last saw the ball, hitting in the tall grass.
170 grs. FG is good for 100 yard.
500 grains of Fg sends the round ball 1100 feet, lasered.
